an overweight man makes lifestyle changes in order to lose weight. his starting weight is 280 pounds and he has set a target weight of 200 pounds. let t be the time in months and let d be the difference in pounds between his weight at time t and his target weight. each month the difference d decreased by 15 %. a make an exponential model of d versus the time t in months since the diet began b How long will it take for his weight to reach 215 pounds?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
